While wary of "cashing in" on the franchise, Global President of 2K Christoph Hartmann suggests that Bioshock could follow the Star Wars saga, generating sequels as long as the story holds out.

Now of course he isn't guaranteeing five more Bioshock games, but Hartmann says that if the innovation is there and the storyline is strong, they would keep telling the Bioshock story until it's done.

“For Bioshock, because it’s so story driven, the question obviously arises: how long can you do it without turning into The Matrix? The first Matrix was great, the second one was weird and the third one, you thought: ‘Who [making this] is on crack and who isn’t?’. “But, then again, look at Star Wars. It’s a fight between good and evil, just like Bioshock. If we spin it the right way and get the right twist of innovation, we can make six parts of it, as Star Wars did.

Hell, if they can keep things fresh and new through five sequels, more of my money to them. Hartmann did go on to say that they would never force out a new Bioshock game just to have a new BioShock game, citing the example of an unnamed racing title.

“But we have to be careful not to cash in. I won’t name the company, but there was a great racing game years ago. They brought it back year-on-year. If you look at the scores, it’s hard to believe what they’ve done to it. It’s upsetting, actually.”
